Abstract
A papermachine fabric for the production of tissue paper or porous batts has a two layer fabric comprised of a fine upper fabric layer and a coarser lower fabric layer. Both fabric layers have a large open area. The two fabric layers are firmly interconnected so that the upper fabric layer exhibits depressions at the sites of interweaving which are distributed in the manner of a pattern. The papermachine fabric is especially suited as an embossing fabric for after drying the paper web coming from a sheet forming fabric or as a second sheet former of a twin wire former.
Claims7
A papermachine fabric for the production of tissue paper comprising two fabric layers interconnected at a plurality of points including a coarse lower fabric layer and a fine upper fabric layer with each fabric layer comprised of woven transverse and longitudinal wires having an open area greater than thirty percent and with the upper fabric layer being interwoven with the lower fabric layer and being drawn into the lower fabric layer to form depressions in the upper fabric layer distributed in the manner of a pattern at the points of interconnection.
